PURPOSE. To evaluate choroidal thickness in healthy pediatric population by swept-source longer-wavelength optical coherence tomography (SS-OCT).METHODS. This was a cross-sectional comparative, noninterventional study. The macular area of 83 eyes from 43 pediatric patients (<18 years) was studied with an SS-OCT prototype system. Macular choroidal thickness was manually determined at 750-lm intervals by measuring the perpendicular distance from the posterior edge of the RPE to the choroid/sclera junction, along a horizontal 4500-lm line centered in the fovea. Three observers independently determined choroidal thickness. Pediatric choroidal thickness was compared with choroidal thickness from 75 eyes from 50 normal healthy adult volunteers (18 years or older).
RESULTS.Mean age was 10 6 3 years (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17) in the pediatric population versus 53 6 16 (25-85) in the adult population (P < 0.001). Mean spherical equivalent was not different (P ¼ 0.06) between both groups. Mean subfoveal choroidal thickness was 312.9 6 65.3 lm in the pediatric versus 305.6 6 102.6 lm in the adult population (P ¼ 0.19). Mean macular choroidal thickness was 285.2 6 56.7 lm in the pediatric versus 275.2 6 92.7 lm in the adult population (P ¼ 0.08). The distribution of choroidal thickness along the horizontal line was different for both populations; the temporal choroid was thicker in the pediatric population (320, 322, and 324 lm; P ¼ 0.002, 0.001, and 0.06, respectively), followed by the subfoveal (312 lm) and nasal choroid (281, 239, and 195 lm).CONCLUSIONS. Macular choroidal thickness in the pediatric population is not significantly thicker than that of healthy adults. Differences are more remarkable in the temporal side of the fovea.

Photodynamic therapy with verteporfin may be useful in chronic CSC for improving BCVA and reducing SRF and CFT. Randomized studies with longer follow-up are needed to assess the real role of this treatment in chronic CSC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
